telemetry(amazonq): update to new module metric name (#6717)

## Problem:

Updated the telemetry types and had to change an existing name to match
the new one.

## Solution:

use `toolkit_didLoadModule` to indicate that the module successfully
opened. In certain cases we will want to use `toolkit_willOpenModule` to
indicate the start of it, but because it doesn't look like that was used
already we can ignore it for now and revisit later.
